GB/T 4089-2008Statistical interpretation of data Estimation and hypothesis test of parameter in Poisson distribution (English PDF)

1 Scope

The overall standard is based on the Poisson distribution, distribution probability mass function is.

P {X = x0/lambda} = lambda

X0! e

-lambda x0 = 0,1,2

Where lambda > 0 is the distribution parameter. X0 independent random sample from this standard based on the overall, x2 ,, x0 shape parameter lambda defines the point estimate

Meter, interval estimation and testing methods. When there is sufficient reason to believe the overall Poisson distribution, we can use this standard.
